‘Wall of Separation’ Phrase Coined

On this date in 1802, President Thomas Jefferson coined the famous phrase describing the Establishment Clause of the First Amendment as erecting “a wall of separation between church and state.” He used the phrase in his famous letter to the Baptists of Danbury, Connecticut, who had asked him to explain the meaning of the First Amendment’s phrase “Congress shall make no law respecting an establishment of religion.”
